JAMES XV. TREV, OF DUBUQUE, IOVA.

PLOW GR HARROW ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 389,121. dated September 4, 1888.

(No model.)

To all whom z' may concern.:

Beit known that I, J .inns WILLIAM Tnnw, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements iu Plow or Harrow Attachments; and I do hereby declare the following to be a full, clear, and exact description ofthe invention,which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a sulky attachmentfor plows, liarrows, the., by means of which a comfortable seat will be afforded the driver, and which can be made very easily and cheaply by any one of ordinary mechanical skill and ability, and, moreover, it can be instantly attached to or detached from the plow, harrow, &c., with which it is to be used.

By the use of my invention the expense necessitated by plowing or harrowing willA be materially diminished by reason of the driver not being so easily fatigued, and further allowing the team to increase its speed, therebeing no back pull on the horses7 heads, as is invariably the case when the driver walks beside them.

Thisinvention relates, further, to a new and improved method of attaching the wheels to their axles, diminishing the expense, and increasing the strength, portability, durability, and general appearance of the device, as well as in other but less important details of construction, all of which will be more fully hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which- Figure l is a perspective view ofthe entire device. Fig. 2 is a sectional view of the axle, showing the manner of attaching the wheels thereto; and Fig. 3, a sectional view illustrating the manner of detachably attaching the device to the plow, harrow, or whatever im-4 plement it is to be used with.

Like letters have reference to identical parts in all of the above views.

A is the seat or saddle on which the driver sits, or, rather straddles, in the manner of one riding a bicycle. rlhis seat is made preferably of wood and of the form illustrated, and is provided in its extreme front end with along annular' chamber, into which the end of the curved iron rod a is inserted. Attached to the extreme rear portion of this seat or saddle A is the axle B, made preferably of metal, though it will be apparent that this axle could be made of wood, provided the requisite strength could be obtained. rlhis axle is provided in cach end with a long` annular chamber, b, and with an intcrnally-screw-threaded opening, c, leading from the outside down into each chamber b. The bearing-pi ns d d, provided with cylindrical heads c c, and on which the wheels C C rotate, arcinscrted into these chanr bers bb, and are each provided with an internally-scrow-threaded opening, ff, therein, extendingdown about hall' through the same,and whicluwhcn all are iu proper postion,will be in line with the scrcwthreaded openings c c, which are of the same internal diameter. A set-screw, g, passed down through the openings c and f and driven tightly home,will now securely lock the bcaringpins d d in place. It will of course be understood that the wheels should be in position on the bearingpins before the set-screws y o are inserted. The iron rod a is locked inside of the chamber in the front portion of the seat or saddle in a similar manner by means of the set-screw h.

I have found by actual manufacture of my device and by practical working of the same that the rod a and axle Il can be made easily and cheaply out of iron or steel piping, and will possess great strength and durability; and I have found, further, from the same source, that old gas-pipe, which can be procured at but slight expense, answers the purpose extremely well.

In Fig. 3 is shown the manner of attaching the device to the plow or barrow, dre.; and it consists, simply, of a pin, i, driven into any convenient portion of the wooden frame-work of the implement, and over which the hollow vertical portion of this rod a lits. It will be evident that in the case of some harrows, in which the teeth extend entirely through the Yframe-work, the hollow end of the rod a can be inserted over any convenient one of these teeth. By either of these arrangements it will be seen that the whole device will trail behind athe implement to which it is attached, and

ICO

will always bein the centerof thelinc of draft, the pin z acting as a pivot.

By the particularl manner of fastening the wheels in place I dispense with the continually-loosening nuts on the end of the aXle which have heretofore been employed, and which are a continual source of annoyance to the farmer, and use instead the integral cylindrical heads e e on the ends of the bearingpins d d.

I do not wish to be limited to a plow or harrow attachment, as my device might be attached to the end of a wagon, so as to form an auxiliary seat; neither do I wish it understood that my device can only be attached to a common farming-plow, as it could be used with good results with a snow-plow.

It is not absolutely necessary to make the saddle A precisely as I have described, as it could be fastened on the end of a leaf-spring, like the seats at present used on mowing-quachines; but to accomplish this would require mechanical and not inventive skill.

Having thus described Inyinvention,whatI claim as new therein, and am desirous of protecting by Letters Patent, is*

In a riding attach ment for plows or harrows, the body or seat having perforations for the Wheelspindles and for the attaching device, in combination with the wheelspindles and their set-screws, and the curved tubular connecting-rod adjustable bya setscrew,whereby the frame is adapted for connection with a plow or harrow, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES w. Tnnw.
